To @ZZ whom it may conceive: v

Be it'known that I, JOSEPH ELoooK, a citizen of the United ,Statesnesiding at Mechanicsburg, in the county of Cumberland and Statek landside, the mold-board, the cutter,`and the s hare.

plow-point in a novel and `effectivev manner; also, to providey certain bearings upon the mold-board and the landside for the handles, and, also, to improve the construction and connection of certain parts of the plow, substantially as described, and shown in the drawings, in which- Y Figure l is a perspective view of my improved plow, showing the mold-board side thereof. Fig. 2 is a side elevation of the plow, showing the landside. view. Fig. .t-is a view from the' rear of 'the plow, the mold-board being in elevation, and the beam and rear portion ofthelandside being shown in section, taken on the line w x, Fig. 2. Fig. 5 is a perspective view of the mold-board,

`with its lower edge turned up, so as to show th'e construction ofthe same. Fig. Gis a bottom view of the mold-board. Fig. 7 is a perspective view, and Fig. 8 an edge view, of the Fig. 9 represents thecutter, which is adapted to be fitted to the, front edge of the mold-board. Fig. l() shows a perspective view and transverse section of the detachable and reversible plow-point. Fig. 1l is a perspective view of a brace-bar to which the rear endV of the plow-beam is adjustably secured. Y

v,The handles A A of this plow are connected bythe rounds a, as usual, and theyare further connected and-braced by a horizontal bracebar, B. rIhe rear end of the beam A rests upon a slotted seat, b', that is formed at one end of' the said brace-bar, and it isadjustably secured upon said seat by means of a bolt, b', which `passes through the beam andthe slot b2 ported.

Fig. 3 is a top or planin the seat, and is provided with a tighteningnut upon its screw-threaded end. The slotted seat is provided with a forwardf extension or lug, b, which rests upon the top of the plowhandle, and is secured thereto by a bolt or other appropriate device. The beam is swivele'd upon the plow by means of a vertical bolt, D, and hence by loosening the nutwhich binds therear end of the beam upon said seat the beam can be turned about its 'pivot to a limited extent in a horizontal plane, so as to bring it into the line of draft, after which it can be Xed in its adjustment by tightening up the nut.

The mold-board E is formed at its top with a ilat bearing, e, upon which the beam is sup- The vertical bolt D,which pivots the beam upon this portion of the plow, passes down through this seat, and also through a lug, e', `(see Fig. 4,) that is providedupon the inner side of the mold-board at a point below thc said bearing e., The mold-board is cut away or recessed at its point or lowerportion of its front edge, as indicated at e?, Fig. 5, and to this recessed point of the mold-board is fitted the cutter F, consisting of a curved rectangular-shaped plate having an oblique iiange or lip, f, (see Figs. 2 and 9,) which laps overthe front edge of the mold-board. The mold-board isalso formed with a vertical iiange, f,which extends back from its front edge.V -The lower portion of this flange and the point of the moldboard on the side next to the landside of the plow are cutaway or recessed, and to this recessed portion of the mold-board is fitted and secured theiiat inner side, g, of the landside G, the latter being formed with'perforations g', for the screws that are employed for fastening the landside and the mold-board together. The landside has a straight edge, g2, above its perforatedA portion g, this said straight edge being fitted against a straight shoulder, c3, Fig; 2, that is formed by recessing thefmold-board on its inner flanged portion; -Theflange-'f of the mold-boardlextends below the -pint of the same, and in the inner side oi'- said extended end of' the flange is formed an inclined 'channel, fwhich receives one edge of the inclined plow-point H. A A y The sole I, that is formed upon the landside, is beveled at its point, as at i, and the landside isformed' with an inclined channel, fi?, just above the sole, said channel being located to constitute a continuation of the channel f 2 in the ilange f of the mold-board when the landside and the mold-board are iitted together.

The plow-point II is fitted between the flat triangular-shaped under side, E', of the moldboard point and the inclined top face of the sole,with one of its edges restingin the grooves f2 of the mold-board and 1' of the landside.

The mold-board is forlned with perl'orations K K near its lower edge and just in rear of the cutter F, and at its inner side, at this perforated part, it is cut away or formed with a shallow triangular-shaped recess, L, in which the inner .end of a triangular-shaped share is fitted and detachably secured by means of screws passing through said perforations.

The share M, which is thus detachably secured to the mold-board, so that after it becomes worn it can be detached and reversed, consists of a fiat triangular-shaped plate having a curved cutting-edge, m, which can be readily sharpened after the share has been detached from the mold-board. rIhe share is formed on each side with a curved rib or shoulder, m, and is cut away upon opposite sides, back of such shoulder, as indicated at m2, said cut-away or recessed part having an inclination toward one of the straight edges ofthe shoe,these recessed portions ofthe share being inclined in reverse directions, so that either side of the share is adapted to lit the mold-board, and hence the share can be accurately secured to the curved recessed portion L of the mold-board in reversing the share.

The double plow-point II, which consists of a long iat bar sharpened at each end, and provided at its middle with several perforations, h, is formed with a longitudinal groove, 1L', running along its opposite edges. Vhen this double-pointed bar is fitted in between the bottom of the mold-board and the sole I, one of the straight edges m" of the share will be received in one of the said grooves of the double-pointed bar, whereby the parts are iitted snugly together and in such way as to give firmness to the structure. \Vhcn one of the ends of this double plow-point becomes worn, the point can be advanced, and, when necessary, it can be taken out and then inserted in a reversed position. rIhe means for securing this double point in place consists of a bolt, N, which passes through and binds together the sole I, the double point H, the mold-board, `and the cutter F, that is fitted upon the recessed point ofthe mold-board in the manner already described. As the face of the cutter is coneaved, t-he head u of this tie-bolt is beveled, so that it will be iush with said face, and upon the lower screw-threaded end of the bolt, below the sole I, will be arranged a washer and a tightening-nut.

y The curved colter O is itted and secured at its upper end by a screw-bolt in a recess that is formed in the ianged side or wing of the mold-board, and is extended down over the plow-point. The landside is formed with an enlargement, l), upon the inner side of its rear portion, and in this enlargement is formed aV -shaped socket, p, which receives the pointed lower end of one of the plow-handles, while upon the inner side of the mold-board is formed an enlargement constituting a bearing, Q, against which the flattened lower end of the remaining handle is held. rlhese said enlarged recessed and plane-faced bearings of the landside and mold-board are perforated tol receive the bolts or screws that are employed for securing the handles in place.

From the above it will be seen that the beam can be readily brought into the line ot' draft, the plow-point H either advanced by passing its securing-bolt through a different hole, or reversed by first taking out the bolt and then removing the point, and that the point, the share, the cutter, the colter, and the landside can all be detached from each other as occasion may require, and any one of said parts be either refaeed or replaced by a new one.

rlhe plow-beam may be stifi'ened by trussrods passing from a point between the attaching bolts under a spreading plate placed against the under side of the beam and above the colter, said plate having end slots to receive the rods, which converge from that point toward the end of the beam, where they may be attached in any suitable manner. 'lhese truss-rods greatly stiien the beam, and plcvent it from springing orbending either laterally or vertically.

Having thus described my invention, what I claim is- 1. The colnbination of the transverse bar I3, having the slotted seat b and extension or lug b, the handles A, the mold-board E, provided with seat c, ilangej", and intermediate lug, e', beam A', and bolt l), passing through beamseat e and lug c', substantially as described.

2. rlhe landsidc G, having the sole I at its front end, the inclined chamber t, arranged above said sole, and the enlargement I and V-shaped socket y, substantially as described.

3, rlhe combination of the mold-board having the iianged portion f', the inclined channel f2, formed in the lower portion of the latter, and the flat upper bearingsurface, E2, located above a portion of said inclined channel, with the reversible plow-point and the landside having the beveled sole I, substantially as described.

4. rlhe combination et' the reversible share M, having the curved shoulder m formed upon its opposite sides, and having the inclined perforated and cut-away inner portion, on?, with the mold-board having the perforated and recessed portion L, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOSEPH ELCOCK.
